The air filter on the HVAC cabinet of your home has a vital job to do—and it isn’t connected to the quality of the air circulating through the house. People often have this misunderstanding: they hear the word filter an imagine the mesh of the filter trapping unhealthy particles in it. You can have HVAC technicians install special indoor air quality filters into the ductwork to remove contaminants from the house—but the one already in place isn’t doing that job.
So what is the filter for? It protects the furnace and air conditioner inside the HVAC cabinet from the dust, lint, and other debris that comes through the return air ducts. After one to three months, the filter will collect enough debris that it must be replaced with a clean one. It’s easy to forget to do this, but we strongly urge you to set reminders for yourself about it. If you leave a clogged filter in place this winter, it can have negative effects on your furnace and lead to furnace repair in Lebanon, OH.
